Regarding early weight loss

Hey there fellow MFP'ers!
I started using MyFitnessPal 6 days ago (currently on a 6 days streak), and noticed yesterday that I had lost 1.2 KG (3 lbs). I was originally 86.2 KG when I had started using MyFitnessPal.

I would like to know whether I am on the "right" weight loss track? I would be disappointed to see if I regain all the weight I had lost after I start to eat normally at my TDEE once I have reached my goal weight of 70-75 KG.

For reference my BMR is around 1800-1850, I usually net around 1300-1400 per day for the past 6 days. I consume around 1400-1500 calories. I do cardio for 24 minutes on the treadmill and burn around 210 calories everyday for the past 6 days (Except one day).
